SECTION 9: LUBRICATION

(See Figure 13)

WARNING: Disconnect the spark plug wire and ground against the engine before performing any lubrication or maintenance.

WHEELS

Oil or spray lubricant into wheel bearings at least once a season. Remove wheels, clean and coat axles with a multi-purpose automotive grease.

CHUTE CRANK

The gear on the end of the chute crank should be greased with multi-purpose automotive grease once a season.

AUGER SHAFT

Lubricate auger shaft at least once a season. Also lubricate the auger bearings at least once a season. Remove shear bolts on auger shaft. Oil or spray lubricant inside shaft.

GEAR BOX

The worm gear box has been filled with grease at the factory. If disassembled for any reason, lubricate with 1.5 ounces of Shell Alvania grease EPR00 (part number 737-0168). Before reassembling, remove old sealant and apply Loctite 5699 or equivalent.

WARNING: Do not overfill the gear box; or damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.

DRIVE AND SHIFTING MECHANISM

Lubricate at least once a season or after every 25 hours of operation. Remove rear cover. Lubricate chains, sprockets, gears, bearings, shafts, and shifting mechanism at least once a season. Use engine oil or a spray lubricant. Avoid getting oil on rubber friction wheel and aluminum drive plate.

HEX SHAFT

Lubricate the hex shaft with Belray 6-in-1grease (available at automotive stores, or order by part number 737-0170) at least once a season or after every 25 hours of operation. If for any reason, the transmission was disassembled and the drive cable disconnected, make sure, while reassembling, to route the cable under the drive shaft and the axle before reconnecting to the support bracket. Important: Keep all grease and oil off of the rubber friction wheel and aluminum drive plate.

ENGINE

Refer to engine manual for all engine lubrication instructions.

WARNING: When following instructions in separate engine manual for draining oil, be sure to protect frame by avoiding oil dripping into transmission parts.
